| 摘 要： | 表面活性剂在固液界面上的吸附作用是十分重要的课题,为此我们开展了这方面的研究[1-3]。沸石结构规则,孔大小均匀,具有特殊的吸附性质。近年来由于作为合成洗涤剂助剂的三聚磷酸钠可使水质富营养化,故国内外都在研究洗涤剂的低磷化措施。

| Abstract: | The adsorption isotherms of tetradecylpyridinium chloride (TPC) from aqueous solutions on the zeolite 5A and the influence of pH, inorganic salts upon the.adsorption of TPC have been studied (at 25℃). The electrophoretic mobilities of zeolite 5A in the same systems have also been measured. The results show that (1) The adsorption of TPC is independent of the pH in the range of 6—11, which is explained by the constant value of electrophoretic mobilities; (2) The Langmuir type isotherms turn into the S type with the increasing concentration of inorganic salts; (3) The surface of the zeolite 5A particle is negatively charged in water. After adding Al3+, the surface charge reverses its sign and the adsorption of TPC decreases markedly. |
